can anybody give me a rough idea of the value of a Bamford 2HP Air cooled hit n miss engine, complete but requiring restoration. I have the chance to buy one but not really sure what I should offer for it? Is there anything in particular I should look out for before making an offer?

1. is it complete enough for you to restore it to running, parts are very hard to source for bamfords as a hole2. price is as always as much as the man with the wallet is happy to pay for it3. value as above as there is no guide prices to many of the engines,unless there common to find4. watch out for the magneto bracket as they can be cracked easy and repaired badly ,also if has a horseshoe magneto make sure it has a good shoe no welds or cracks in it and hope it has enough magnitism to hold a 13mm nut
